[0048] The embodiments of the utility model will be described in detail below with reference to the drawings.

[0049] The utility model embodiment provides a vehicle body height sensor, please refer to Figures 1-5 . The vehicle body height sensor includes sensing assembly, base assembly, extension unit and positioning assembly.

[0050] Specifically,

[0051] The sensing assembly includes a height sensor 10, a mounting bracket 11 and a sliding block 12. The mounting bracket 11 is sleeved and fixed to the outer wall near the bottom of the height sensor. Two outer side walls of the mounting bracket 11 are respectively connected with a sliding block 12. One side wall of the height sensor 10 is rotatably connected with one end of a swing arm support, and the other end of the swing arm support 13 is mounted on the automobile suspension. The mechanical movement of the vehicle body drives the rotation of one end of the swing arm support, and the height sensor 10 generates a corresponding electrical signal and outputs to the automobile control system to feedback the current height of the vehicle body.

[0052] The base assembly comprises a base body 20, a first slide rail 21 and a second slide rail 22 and a buffer block 23. Each slide rail side wall is provided with a sliding groove 221 matched with the sliding block 12, so that the sliding block 12 can be clamped into the sliding groove 221. The height of the first slide rail 21 is lower than that of the second slide rail 22. The first slide rail 21 and the second slide rail 22 are matched with the two sliding blocks of the mounting frame 11 and are arranged on the top surface of the base body 20, so that the mounting frame 11 can slide between the first slide rail 21 and the second slide rail 22, thereby driving the height sensor 10 to slide along the extension direction of the slide rail. The sliding limit of the height sensor at the base body can be achieved by movably installing the buffer block 23 on the side wall of the second slide rail towards the height sensor, and the bottom end of the buffer block extends to be fixed with the base body 20. In order to reduce the shaking amplitude of the height sensor in the base assembly, the side wall of the second slide rail towards the height sensor is penetrated by a buffer groove 220 extending along the extension direction of the base body; the second slide rail 22 is provided with a buffer pad 24 matched with the buffer groove 220; and the buffer pad 24 is installed between the buffer block 23 and the height sensor 10.

[0053] The extension unit is rotatably connected to the side wall of the base body 20 in the extension direction thereof, wherein the extension unit can be rotated to the top surface flush with the top surface of the base body, so that the sliding distance of the height sensor 10 on the base body 20 is increased. The extension unit can also be rotated below the base body 20 and fixed by screwing with the base body 20. Each extension unit comprises a connecting plate 34 and an extension plate assembly.

[0054] The connecting plate 34 is installed on the side wall of the base body 20 in the extension direction of the slide rail, and the first rotating shaft 33 is fixed at the bottom end thereof. The end surface in the axial direction of the first rotating shaft is provided with a rotating groove.

[0055] The extension plate assembly is arranged at least on one side wall of the base body in the extension direction thereof, and the two side walls of the extension plate assembly are rotatably connected with a connecting plate 34, respectively. The connecting plate 34 is installed on the side wall of the base body, so that one extension plate assembly can be rotatably connected with the base body 20. The extension plate assembly has a second rotating shaft 35, an extension plate body 30, a fixing block 31 and a mounting piece 32. Among them,

[0056] The second rotating shaft 35 is matched with the rotating groove, so that the two first rotating shafts of the connecting plate 34 are respectively inserted into the corresponding second rotating shaft 35, and are rotatably connected with the second rotating shaft 35.

[0057] The extension plate body 30 is connected with the second rotating shaft 35 respectively at two side walls of the first rotating shaft, and is rotationally connected with the base body 20 through the rotation connection between the second rotating shaft 35 and the first rotating shaft 33. Moreover, the extension plate body 30 is arranged between the two connecting plates 34 in matching with the base body 20, that is, when the second rotating shaft 35 rotates clockwise or counterclockwise relative to the first rotating shaft 33, the extension plate body 30 can rotate in the same direction with the second rotating shaft 35, and under the adjustment of the rotating amplitude and direction of the second rotating shaft 35, the extension plate body 30 can be rotated upward to the top surface of the base body 20 or downward to the bottom surface of the base body 20.

[0058] The fixed block 31 is connected with the top surface of the extension plate body, and is used for fixing with the slide rail. When the second rotating shaft 35 rotates relative to the first rotating shaft 33 to drive the extension plate body 30 to rotate upward to the top surface of the base body 20, the fixed block 31 is fixed with the corresponding slide rail, so that the length of the slide rail is extended. Each fixed block 31 is provided with a sliding groove 221 matched with the sliding block 12.

[0059] The mounting piece 32 is connected with the side wall of the extension plate body. When the second rotating shaft 35 rotates relative to the first rotating shaft 33 to drive the extension plate body 30 to rotate downward to the bottom surface of the base body 20, the extension plate body 30 is fixed to the bottom end of the base body 20 through the bolt connection between the mounting piece 32 and the base body 20, so that the space is saved.

[0060] When the sliding distance of the height sensor 10 along the slide rail needs to be lengthened, the bolt between the mounting piece 32 and the base body 20 is removed, the extension plate body 30 is rotated to the top surface of the base body 20, and the fixed connection between the fixed block 31 and the slide rail is used to realize the lengthening.

[0061] The positioning assembly is connected with the side wall of the second slide rail 22 away from the sensing assembly at one end, and is matched with the connecting end of the vehicle chassis support at the other end to be installed. The positioning assembly comprises a connecting rod 40 and a mounting column 41. One end of the connecting rod is fixed to the second slide rail 22, the other end of the connecting rod extends transversely, and the mounting column 41 is connected at the end of the other end of the connecting rod. The mounting column 41 is provided with a mounting hole 410 penetrating along the axial direction of the mounting column 41. The positioning assembly is installed at the vehicle chassis support through the bolt connection between the mounting hole 410 and the connecting end of the vehicle chassis support.

[0062] Based on the above embodiment, the working principle of the application is as follows:

[0063] The sensing assembly with the swing arm support 13 rotatably connected to one side wall is arranged between the two slide rails, the slide base body 20 is adjusted to adjust the position of the mounting hole 410 until the connecting end of the vehicle chassis support is aligned, in the above adjustment process, the slide distance of the slide base body 20 can be lengthened by rotating the extension plate body 30 upward to the top surface flush with the top surface of the base body and then fixed with the slide rail, so as to further ensure that the slide base body 20 has sufficient slide distance. The mounting hole 410 and the connecting end of the vehicle chassis support are bolted. In the process of driving the automobile, the mechanical movement of the vehicle body drives the rotation of one end of the swing arm support, the height sensor 10 generates a corresponding electrical signal, and outputs to the automobile control system to feedback the current height of the vehicle body.

[0064] Based on the above embodiment, the advantages of the present application are:

[0065] (1) The rotation connection of the extension plate body 30 and the base assembly can lengthen the slide distance of the base assembly relative to the sensing assembly, so as to provide sufficient adjustment distance for the mounting column 41 to align and install with the vehicle chassis support, and improve the assembly efficiency.

[0066] (2) The above-mentioned sensing assembly is additionally provided with a base assembly, and the extension unit is installed at the slide rail of the base assembly to install with the vehicle chassis support, so as to replace the traditional height sensor directly installed with the vehicle chassis support, and the buffer pad 24 is additionally arranged between the height sensor 10 and the slide rail to reduce the interference degree of the shaking of the height sensor in the process of the movement of the vehicle body on its own detection.
